The Italian Society of Pediatric Surgery (SICP) together with The Italian Society of Pediatric Anesthesia (SARNePI) through a systematic analysis of the scientific literature, followed by a consensus conference held in Perugia on 2015, have produced some evidence based guidelines on the feasibility of day surgery in relation to different pediatric surgical procedures. The main aspects of the pr...

Rotary ultrasonic machining is a cost-effective and precise method for hard brittle materials. Aiming at processing SiCp/Al composites, rotary grinding spindle proposed in the present study. Expressions were established to calculate displacement, rotation angle, bending moment, shear force of vibrating elements based on Mindlin moderately thick plate theory. Combining continuous boundary condit...

By hot extrusion at 250°C and electrical pulse treatment (EPT) of 40 ?s duration 10 min processing time, a homogeneous matrix microstructure with an average grain size 0.91 ?m abundant Mg17Al12 phase was obtained in SiCp/AZ91 magnesium composite. Moreover, SiCp were helpful to promote the accumulation crystal defects precipitation phase. After 250°C, yield strength (YS) ultimate tensile (UTS) c...

The Steady state creep behaviour of a functionally graded cylinder made of isotropic composite containing varying distribution of silicon carbide particles has been investigated by a mathematical model. The creep behaviour of the FGM is described by a Norton's Power law. The effect of varying distribution of SiCP particles of creep stresses and creep rates in the FGM cylinder has been anal...
